Explanation:

When production costs decrease, suppliers are willing to offer more units which causes the supply quantity to increase. Then, the price will decrease so the suppliers will be able to sell the quantity offered.

A relative price is the price of a product or service in terms of another one. For example, if a cappuccino costs $2 and a coffee $1, the relative price is 2:1 which means that when you buy a cappuccino you lose out on 2 coffees.
